Technical Field
Macadamia nuts, also known as macadamia nuts, are originally produced in australia, are top-grade edible nuts in the world, are favored by consumers due to excellent nutritional characteristics and flavor quality, and are reputed as "king of nuts" and "best edible nuts in the world". China began to plant macadamia nuts commercially in the late eighties of the twentieth century, mainly focusing on Yunnan and Guangxi. The macadimia nuts are planted in the tropical zone of China, and the method has remarkable economic benefit and is rare and special economic tree species suitable for being planted in the tropical zone of China.
Grafting is one of the asexual propagation methods, that is, the branch or bud of the excellent variety is grafted to the proper position of another plant, and the two are combined to produce new plant. The grafted branch or bud is called scion or scion bud, and the plant connected with the scion or scion bud is called stock. By adopting the grafting propagation method, the propagation speed is high, and the excellent properties of the scion stock plant and the favorable characteristics (such as stress resistance, adaptability, early bearing property and the like) of the rootstock can be maintained.
For macadimia nuts, most of the existing traditional grafting technologies adopt 5-10cm bud grafting/short connection, the grafting survival rate is low, the bud survival rate under strict management is within 70%, the loss is large, large-area planting is not facilitated, cultivation is required to be carried out for about 24 months after grafting, and the cultivation speed cannot meet the requirements at the present stage.
